Filter by:The purpose of this study is to determine whether Umbilical Mesenchymal Stem Cells (UMSCs) derived Exosomes could alleviate dry eye symptoms in patients with chronic Graft Versus Host Diseases (cGVHD).
This study will be a randomized, double-blind prospective in 3 clinical sites to compare the efficacy of two currently approved topical ophthalmic drops in the clearing central corneal staining in 90 days prior to elective cataract or LASIK surgery.
Knowledge of the pathogenesis of ocular conditions, a leading cause of blindness, has benefited greatly from recent advances in ophthalmic imaging. However, current clinical imaging systems are limited in resolution, speed, or access to certain structures of the eye. The use of a high-resolution imaging system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many microstructures of the eye: photoreceptors, vessels, nerve bundles in the retina, cells and nerves in the cornea. The use of a high-speed acquisition imaging system makes it possible to detect functional measurements such as the speed of blood flow. The combination of data from multiple imaging systems to obtain multimodal information is of great importance for improving the understanding of structural changes in the eye during a disease. The purpose of this project is to observe structures that are not detectable with routinely used systems.
This is a single site, prospective, cross-sectional, controlled clinical study on a total of 66 subjects. The subjects are divided into two groups: Hypertonic Saline Non-Responders (33 subjects) and Hypertonic Saline Responders (33 subjects). After completion of questionnaires, the subjects will undergo Dry Eye Disease testing and functional nerve testing. Subjects who qualify will be dispensed 4 weeks of preservative free artificial tears and instructed to instill one drop into each eye twice daily. Subjects will return for a follow up visit 4 weeks later (± 4 days), during which subjects will complete the questionnaires again and the Dry Eye Disease tests and functional nerve tests will be repeated.
Dry eye is a common ocular surface disease of multifactorial etiology characterized by elevated tear osmolality and inflammation leading to a disrupted ocular surface. The latter is a risk factor for ocular surface infection, yet overt infection is not commonly seen clinically in the typical dry eye patient. This suggests that important innate mechanisms operate to protect the dry eye from invading pathogens. Understand the pathogenesis of dry eye will be the measure to prevention and treatment of dry eye. In this essay, the investigators use the data of experiment in the patients with dry eye and normal, acquire their tear production, tear film stability, and surface damage. The investigators use weka to calculate the prediction accuracy of the 6 algorithm and select the best one, optimize the parameters to get the final prediction accuracy.
This study was conducted to investigate the effects of daily supplementation of Hydrolysed Red Ginseng Extract extract on dry eye.
This study aims to elucidate the effectiveness of oral azithromycin in treating symptomatic dry eye syndrome secondary to Meibomian gland dysfunction.
This trial is a randomized, parallel-group, double-blind, controlled clinical trial to evaluate the effect of hyaluronic acid (HA) on dry eye disease.
In this study, the TearCare System will be compared with the LipiFlow Thermal Pulsation System in patients with dry eye disease. The objective is to demonstrate that the TearCare System is safe and effective in relieving the signs and symptoms of dry eye disease. NOTE: All sites have been selected for this study. We are not seeking additional sites at this time.
Portable USB-powered eyemasks provide convenience to dry eye sufferers to perform eyelid warming at home. Such eyemasks can be plugged into a copyrighted device developed in collaboration with Ngee Ann Polytechnic that tracks patients' usage. This revolutionary device transmits a signal and is sent to a cloud system whenever the device is used and activity of usage will be recorded. The cloud database only allows access to administrator and will be password protected. You or your physician can monitor the frequency of eyelid warming over a long period.
